Here's why:
* Erosion is the process of wearing away and transporting material. This could be rocks, soil, sand, or other sediments. The agents of erosion include wind, water, and ice.
* Deposition is the process of dropping or settling of eroded material. This happens when the transporting force (wind, water, etc.) loses energy and can no longer carry the material.
So, here's the connection:
* Erosion moves material.
* The transporting force eventually loses energy.
* When the force loses energy, the material is deposited.
However, not all eroded material gets deposited immediately:
* Some material might be transported over long distances. For example, sediment eroded from mountains can end up in the ocean after being carried by rivers.
* Some material might be lost permanently. For example, material eroded by wind can be blown into the atmosphere and never deposited.
Therefore, while erosion is often followed by deposition, the two processes aren't always directly linked.
